s3:smbclient: Allow last dos attribute to be cleared

Browse Source 
With the upgrade to SMB3.1.1 from cifs for smbclient,
setmode no longer works when removing attributes,
if the resultant attribute is 0 it is skipped
(unlike for the old cifs setpathinfo).

When clearing the final attribute, pass in ATTRIBUTE_NORMAL
instead of zero.

This also removes a redundant cli_setatr call
when clearing attributes (cli_setatr was being called
twice).
